TAKE-UP STOP-MOTION.

Application filed December 2, 1919.

To all whom it may concern:

Be it known that we, HUGO RICHARD i BAUER, a citizen of the United States, and

HERMAN FRANZ RnINHoLD, a citizen of the United States, and both residents of Cllfton, in the county of Passaic and State of New Jersey, have invented a new and Improved Take-Up Stop-Motion, of whlch the following is a full, clear, and exact descrlption. 7

The invention relates to power looms provided with a stop motion, and its object is to provide a new and improved take-up stop motion arranged to prevent the formation of a defective fabric by rendering the take-up inoperative and thereby preventing it from advancing the woven fabric in case the filling or weft threads breaks or runs out in the shuttle.

Another. object is to prevent the weaver" from restarting the loom unless the stop motion for the take-up is first reset.

Another object is to enable the weaver to quickly determine'whether the loom was stopped by the usual warp-controlled stop motion or by the usual filling-controlled stop motion, thus enabling the weaver to quickly make the necessary repairs.

of construction as hereinafter shown and' described and then specifically pointed out in the claims. I

A practical embodiment of the invention is represented in the accompanying .drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

t1on, the parts being shown in position when the loom is running;

F1g. 5 is a cross section of the same on the line 55 of Fig. 4;; and

Fig. 6 is a sectional side elevation ofthesame with the parts in position after the loom is stopped by the usual 'filling controlled stop motion.

In power looms for weaving cloth or other fabrics, and as now generally constructed, use is made of a warp-controlled stop motion and a weft or filling-controlled stop motion to stop' the loom automatically 111 case the warp or the filling breaks, or the filling runs out inthe shuttle. During the time the filling stop' motion begins to act until the'loom comes to a dead stop, the take-up remains in action and the woven fabric is advanced with a consequent defect in the fabric either through no filling in thepick and a consequent thin portion in the weave, or with two wefts in the same. Pick and a consequent increase in the thickness of the weave owing to the carelessness of the weaver 1n the proper ad ustment of the take-up. In order to prevent this defect'in the weave, use is made of a take-upstop motion, presently described in detail, and arranged to quickly render the take-up inop-' erative and thus prevent an undesired advance of the fabric untl the loom is'againin proper working order and the take-up stop motion is reset.

The power loom on which the take-up stop motion is shown applied is provided 12 actuated from the usual crank shaft of the loom. The ratchet wheel 10. is engaged by a pawl or a catch 15 to prevent return movement of the ratchet wheel 10 and consequent unwinding of the cloth woven and passing around the guide cloth .roll 16 and the sand roll 17, to wind up on the bottom roll 18 in the usual manner, and which rolls 17 and 18 are driven from the take-up ratchet wheel 10 by the usual gearing 20, as indicated in Fig. 1. The power loom is, further provided with a stop mo= tion controlled by the filling, and such, for instance, as that known as the Knowles center stop motion adapted to actuate the I is likewise in engagement with the said shippershaft provided at each end with .a shipper handle 26' and journaled in the main frame 29 and in a bracket 27 attached to the underside of the usual breast beam 28 attached to the loom frame 29 at the front end of the machine above the take-up mechanism. The filling controlled stop motion is provided with atumbler finger 30 fastened to the shipper shaft 25 and actuated by a pin 31 projecting from the tumbler 32 adapted to be actuated by the dagger 33 controlled by the feeler wires whenever the filling breaks or runs out to stop the loom.

The take-up stop motion is presently described in detail and is controlled bythe pin 31 of the tumbler 32 and connects with the pawl or catch 15 to lift the latter out of engagement with the ratchet wheel 10 im-.

.mediately after the tumbler pin 31 begins,

to actuate the tumbler finger 30. For the .purpose mentioned use is made of a shaft 40 journaled in suitable bearings 41 and 42, of which the bearings 41 are secured to the -main frame 29 while the bearing 42 is attached to the breast beam 28 approximately at the middle thereof. On this shaft .40 is secured a tumbler finger 43 extending with 7. its free end under the tumbler pin 31 at the 30V time the' loom is running, and the other tumbler finger 30 of the filling stop motion tumbler pin 31, as plainly shown in Fig. 4. On each end of the shaft 40 is secured a lift ing arm 45 in which is adjustably held an 7 eye bolt 46 by the use of nuts 47 and 48, and

this eye bolt 46 is connected by a chain or set screw 56 on a bracket 57 adjustably se-' cured by a bolt 58 to the top of the loom frame 29 adjacent the corresponding end of the "breast beam 28. The bolt 58 extends through a slot 59 formed in the corresponding bracket 57 to allow of adjusting the lat ter forward orbackward to correctly posi tion the arm 55, which latter is held trans- I versely adjustable on the bracket 57 to cor rectly locate the shipper retaining member 53 and its pin 52 relative to the slotted arm 50.. The pivoted member 53 is provided at its inner side with a pin 60 engaged at its under side by the V-shaped top of a rod 61 V mounted to slide at its lowerend in a bearingv 62 forming part of the arm 55' of the bracket 57. A spring 63-is coiled on the rod 61 and is seated at its lower end on the bearing 62 and presses at its upper end on a shoulder 64 formed on the rod 61 thus exerting an upward push on the rod 61 with a view to move the pivoted member 53 quickly into an uppermost horizontal position, as hereinafter more fully explained.

The member 53 has a rule joint connection with the arm 55 to limit the swinging movement of the pivoted member 53.

WVhen the pivoted member 53 is in uppermost and approximately horizontal position, as shown in Figs. 2, 3 and 4, then its free end extends into the path of the shipper handle 26 at the time the latter is in stopped position (see Figs. 2 and 6) to prevent the weaver from moving the shipper handle 26 from the stopped position into starting position. In order to enable the weaver to start the 100m it is necessary for him to swing the pivoted member 53 downward into an approximately vertical position, shown in Figs. 1, 4 and 5, to allow the weaverto move the shipper handle 26 from the stop position into starting position to re-start the .loonn lVhen the member 53 is swung into an a p' proximately vertical position it is'held therein by the spring-pressed rod 61 (see dotted lines in Fig. 2) and when a rocking motion "is given to the shaft 40 by the tumbler finger 43 then the arm 50 imparts a swinging motion to the member 53in a rearward direction, and as soon as the spring-pressed rod 61 has passed the vertical position then it is forced upward by its spring 63 and thus quickly swings the member 53 into uppermost position thereby imparting a quick swinging movement to the arm 50 to quickly a rock the shaft 40 and'therebycause the lifting arm 45 to exert an upward pull on the flexible connection 49 to swing the pawl or catch 15 upward out of engagement with the ratchet wheel 10. Thus the ratchet pawl 15 is lifted out of engagement with the ratchet wheel 10 prior to the loomcoming to a stop in case thefilling breaks or'runs out. The shipper shaft 25 is actuated by its tumbler finger 30, in the usual manner. It will be noticed that as soon as the pawl 15 is swung out of engagement with the ratchet wheel 10, the take-up mechanism becomes inoperative and consequently the woven cloth is not advanced to'prevent a defect in the cloth by the'inissing of a filling or by subsequently placing two fillings in the same pick.

It is understood that when the loom is running, the shipper handle 26 is approximately in a vertical position, as shown in Figs. 4 and 5, and the two tumbler fingers 30 and 43 are bothinengagement with the 7 tumbler'pin 31, and the pawl 15'isin engagement with the ratchet wheel 10. Now in case the filling breaks and runs out of the shuttle, the dagger 33 is actuated by the feeler wires and a downward swinging movement V is given to the tumbler. 32' whereby both tumbler fingers 30 and 43 are swung downward to rock the shafts 25 and 40; The rocking of the shaft 25 causes a stopping of the loom and the rocking of the tumbler finger 48 causes a quick lifting of the pawl 15 out of engagement with the ratchet wheel 10 so that the take-up mechanism is rendered inoperative prior to the stopping of the loom.

It will be noticed that when the shaft 40 is actuated, as above explained, the retaining member 53 for each shipper handle 26 is moved into an approximately horizontal position thus holding the tumbler finger-43 in lowermost inactive position, as shown in Fig. 6, at the same time preventing return movement of the shipper handle '26. Now in order to re-start the loom by pulling the shipper handle 26 into vertical position it is necessary for the weaver to swing the retaining member'53 downward into an approximately vertical position to rock the shaft 40 in a reverse direction and thus allow the pawl 15 to swing back into engagement with the ratchet wheel 10 and to move the tumbler finger 43 back into engagement 'with the tumbler pin 31. It will also be noticed that by the use of the retaining 'member 53 the weaver can quickly see affected on the warp stop motion being actuated but only when the filling stop motion is actuated, as above explained. It will further be noticed that the take-up stop mos tion can be readily attached to a loom now in use and without alteration in the construction thereof.

A brake mechanism for quickly stopping the loom is not necessary as the take-up is rendered practically inoperative prior to the loom coming to a stop and hence the cloth is not advanced.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.
